...Security is a main concern with VoIP, as it is with other Internet technologies. The most prominent security issues over VoIP are identity and service theft, viruses and malware, denial of service, spamming, call tampering and phishing attacks. Analysis of Cloud Computing In a cloud computing system, there's a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The network of computers that make up the cloud handles them instead. Hardware and software demands on the user's side decrease. The only thing the user's computer needs to be able to run is the cloud computing systems interface software, which can be as simple as a Web browser, and the cloud's network takes care of the rest. There's a good chance you've already used some form of cloud computing. If you have an e-mail account with a Web-based e-mail service like Hotmail, Yahoo Mail or Gmail, then you've had some experience with cloud computing. Instead of running an e-mail program on your computer, you log in to a Web e-mail account remotely. The software and storage for your account doesn't exist on your computer, it's on the service's computer cloud. When talking about a cloud computing system, it's helpful to divide it into two sections: the front end and the back end. They connect to each other through a network, usually the Internet. The front end is the side the computer user, or client, sees. The back end is the "cloud" section of the...

...Jennifer Strangmeyer INF 103 Professor Gee 3 March 2013 Cloud Computing Cloud computing is a combination of software and computing delivered on demand, as a service. Its intention is to increase your organizational agility rapidly and cut back on cost of hardware. As all new things, Cloud computing has its pros and cons, but I feel in the long run and if properly used, it is beneficial. Cloud computing refers to applications and services offered over the Internet. These services are offered from data centers all over the world, which collectively are referred to as the "cloud." This metaphor represents the intangible, yet universal nature of the Internet. The idea of the "cloud" simplifies the many network connections and computer systems involved in online services. In fact, many network diagrams use the image of a cloud to represent the Internet. This symbolizes the Internet's broad reach, while simplifying its complexity. Any user with an Internet connection can access the cloud and the services it provides. Basically, instead of storing all of your information on your phone, hard drive, etc. and taking up space, you can store it in a “cloud”. Otherwise known as a server. Companies purchase server space (i.e. Cloud) instead of actual hardware to back up their files. A cloud computing solution can help your organization at home or your work achieve multiple benefits, including: * Faster time to market due to on demand deployment * Cost Structuring: Predictable...

...Andrew Marty Cloud Computing Cloud computing is becoming the "solution" for businesses. It is revolutionizing how businesses work & get things done. Before cloud, computing was ever thought of, businesses worked from their own computers, licensing tons of software & people complaining that their computers were too slow to handle the proper tasks they needed to get finished. Fast forward years later, now were in the cloud-computing era. The era where people can access tons of applications through a remote server. Where companies can save money, license the program they need once & where there are no complaints about it being slow to the extent where they cannot use certain programs because of memory issues. There are tons of advantages cloud computing has in the business world & that is what I will be elaborating on throughout this essay. When talking about cloud computing in the business world, it is helpful & understandable to divide it into two sections, which are the front end & the back end. They connect to each other through a network. The front end is the side the person see's, like the computer & the applications used to run the computer & which ones to access the cloud. The back end consists of various types of technology such as the computers, the servers & the data storage systems that create the cloud. This architecture is involved for creating a cloud-computing environment. A cloud-computing environment is especially great...

...making computing easy and eliminating the need to sit in front of a desktop or lug around storage mediums such as cds. Mark Weiser, most often referred to as the father of ubiquitous computing (ubicomp), coined the term in 1988. Ubiquitous means to exist everywhere at the same time or to be constant. His forward thinking brought about the possibility to compute on the go and from nearly anywhere. Innovation news daily provides readers with insight on innovative technologies and inventions that shaped ubiquitous computing and many other technologies. In an article entitled “In the Future, Computing is (Cunningly) Constant”, the details of ubiquitous computing are outlined. It also features contributing components and the effect of such an evolution in lifestyles and business. Ubiquitous computing has been “under construction” for more than two decades. According to the article, it originated in a Xerox PARC research lab where the father of ubicomp (Weiser) worked. Innovation news refers to it as a state in which mobile devices such as the IPAD combine forces with high speed internet connections, Google docs, and cloud computing to reduce the need for the computer in the computing process. Along with eliminating the need for the computer, ubicomp in the years to come is expected to save the consumer space, on the desk and the headache of trying to find a computer and systems that work for your lifestyle. Consumers will shop for data systems such as cloud computing that allows...

...[pic] Cloud computing in general isn’t a term that can be defined with one specific definition as different people from all over the world each have a different understanding of the term cloud computing. Hence the best way to effectively explain the term is to explain it using different examples. Some people believe the term to mean another way of describing IT (information technology), others use it to mean any computing service provided over the Internet or a similar network; and some define it as any bought-in computer service you use that sits outside your firewall. As you can seem, there is no straightforward definition for the term and therefore best way to understand it is to learn about how it works. The main point of cloud computing can be summed up with this one short sentence: “Access your data anytime and anywhere” What is the difference between cloud computing and old fashioned personal computing? An important thing that differentiates cloud computing to the now old fashioned and declining personal computing is the location where all the data is stored. In cloud computing the data is stored on a remote database operated by a third party which can be accessed from most places, as the main requirement to access this cloud storage is only an Internet connection. In personal computing, all data is stored on a hard drive or another form of data storage device such as a usb drive, and once the data storage limit is reached a bigger hard drive...

...EBM510 - Information Processing and the Web Cloud Computing Research Paper Mahesh BahuleyanNair 000-14-6974 Abstract This research paper is to recommend or suggest cloud computing as an alternative to the obsolete and highly expensive traditional computing mechanisms. Cloud computing is a new general purpose Internet-based technology through which information is stored in servers and provided as a service and on-demand to clients. Cloud computing services including Infrastructure as a Service promise potential cost savings for businesses by offering remote, scalable computing resources. However attractive these services are, they pose significant security risks to customer applications and data beyond what is expected using traditional on-premises architecture. This paper identifies three basic types of threats related to the IaaS layer and eight kinds of attacks. These are aligned within the CIA model as a way to determine security risk. Cloud computing is a generalized term for anything that involves delivering hosted services over the Internet. These services are broadly divided into threesome categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The study darken computing was inspired by the darken symbol that's often utilized to equal the Internet in flowcharts and diagrams. A darken assist has threesome...

...Cloud Computing Introduction This term paper will describe the characteristics of Cloud Computing and services associated with it. It will cover how businesses deploy services such as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS), as well as some of the benefits and challenges of Cloud Computing. Cloud Computing Definition - Cloud Computing is basically servers providing specific services to businesses and individuals over the internet. Characteristics * Shared Infrastructure — is when data centers use virtualization software on existing servers. This cuts down on total cost of infrastructure, storage, and networking bandwidth. * Dynamic Provisioning —Server computing instances or virtual machines are provisioned dynamically from a centralized console using automated software. The amount of services provided are determined by current demand requirements. * Network Access — One thing I like about Cloud Computing is the ability to access your account from anywhere, from any device. As long as you have an internet connection, you can use your pc, tablet, laptop, or mobile devices. An example is using iCloud storage to backup and restore your iphone. * Managed Metering — Another thing I like about Cloud Computing is you are only billed for what you use. Metering is used to optimize the service, provide reporting, and billing information. Service Models Once a cloud is established, how...

UC Berkeley {ychen2, vern, randy}@eecs.berkeley.edu ABSTRACT While the economic case for cloud computing is compelling, the security challenges it poses are equally striking. In this work we strive to frame the full space of cloud-computing security issues, attempting to separate justified concerns from possible over-reactions. We examine contemporary and historical perspectives from industry, academia, government, and “black hats”. We argue that few cloud computing security issues are fundamentally new or fundamentally intractable; often what appears “new” is so only relative to “traditional” computing of the past several years...

...To: Mari Buche, Colleague From: Kristen Therrian, Colleague Date: October 20, 2014 Subject: Cloud Computing The world of cloud computing has recently become of interest in my research. I would like to hear from you on whether cloud computing is something I should pursue after discussing what cloud computing is, what is the cloud computing system architecture like, what are its advantages, and disadvantages. The article reviewed shows that cloud computing is a network of computers that handles the brunt work of running applications. Companies need only to install one application that lets employees log onto a web-based service, such as the internet which hosts all the programs that users would need. The interface software which is like a browser, is the only thing that is needed. The network of the cloud will take care of everything else. The cloud architecture has a back end and a front end. The back end allows users to connect to the internet or network. It is also where numerous servers, computers, and storage systems are located that build the “cloud” of the computing system (Strickland, 1998-2014). The front end is what the user can view and it is where the client’s computer and the application that is the means of entry to the cloud system is located. It is important to note that each application acquires its own server. The central server manages the system where it audits traffic and demands of clients to guarantee everything runs properly. The central server...

...Green computing, green IT or ICT Sustainability, is the study and practice of environmentally sustainable computing or IT. In the article "Harnessing Green IT: Principles and Practices", San Murugesan notes that this can include "designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems — efficiently and effectively with minimal or no impact on the environment."[1] The goals of green computing are similar to green chemistry: reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote the recyclability or biodegradability of defunct products and factory waste. Many corporate IT departments have green computing initiatives to reduce the environmental impact of their IT operations.[2] Green ICT and its services present opportunities to deliver low carbon footprints and mitigate carbon emissions because of the unique ability to make energy consumption and green house gas emissions visible through its products and services.[3] Definition - What does Green Computing mean? Green computing is the environmentally responsible and eco-friendly use of computers and their resources. In broader terms, it is also defined as the study of designing, manufacturing/engineering, using and disposing of computing devices in a way that reduces their environmental impact. Many IT manufacturers and vendors are continuously...

...Cloud Computing Cloud computing is being hailed as an important technological shift which promises to change the face of information technology and data management in not only unprecedented ways but also in ways which are yet to be conceived. In other words, cloud computing is believed to offer a world of limitless potential and opportunity which may transform the ways in which businesses handle, store, access and manage data and the ways in which they deploy the necessary hardware, software and liveware assets for achieving their organizational goals. Cloud computing refers to the capability to deliver computing as a service, be it raw computing power, generic or specialized software, or storage space. This delivery is done through an interconnected network of computers to users who pay for the respective services as per their use. The reason that these services are known as ‘cloud’ is that the users typically do not know the exact location of their data / programs (all they know is that it is somewhere ‘out there’, or ‘on a cloud’). Status Quo - On-Premises Traditionally, most of the computing structures of the business organizations were designed as on in-premises systems. This comprised arrays of servers (number, size and power depending upon the size and computational requirements of the respective organizations), software (generic as well as customized) installed on those same servers and / or workstations, and storage capacity housed in the same place (usually)...
